Why You Should Wash New Underwear

1. Potential Irritants and Allergens

New underwear can come into contact with various chemicals during the manufacturing process. These can include dyes, fabric softeners, and other treatments that may cause skin irritation or allergic reactions. According to sources like www.realsimple.com and inthewash.co.uk, such irritants can lead to discomfort, including rashes or dermatitis, particularly for sensitive skin.

2. Microbial Contamination

As noted by experts in www.self.com and www.wellandgood.com, garments can harbor bacteria and other microbes from production to the retail shelf. Washing your underwear helps reduce the risk of exposure to these potentially harmful organisms, ensuring better hygiene. Germs can be transferred from various sources, including handling by store staff, previous customers, or even during shipping.

3. Residual Chemicals

Clothing often contains residual chemicals like pesticides and flame retardants from the manufacturing process. According to reports from www.consumerreports.org, washing your new underwear can help eliminate these chemicals, reducing the risk of skin reactions and promoting overall health.

How to Properly Wash New Underwear

1. Read Care Labels

Before washing, always check the care labels on your underwear for specific instructions. Different materials may have different washing requirements. For instance, lace or delicate fabrics may require a gentle cycle or hand washing, while cotton can usually handle a warm wash.

2. Use Mild Detergents

Opt for mild, hypoallergenic detergents to minimize any potential skin reactions. Avoid harsh chemicals and fragrances that can irritate sensitive skin. Many brands, as discussed on www.rd.com, offer detergents specifically formulated for delicates, which are ideal for underwear.

3. Separate Colors

To prevent color bleeding, wash new underwear separately from other garments, especially if they are brightly colored. This practice is supported by guidelines from www.thespruce.com, ensuring that your whites remain bright and your colors do not bleed.

4. Drying Tips

Air drying is often the best method for drying delicate underwear, as high heat from dryers can damage elastic and fabrics. If you must use a dryer, opt for a low heat setting and remove the underwear while still slightly damp.

Common Misconceptions About Washing New Underwear

1. They Are Clean Because They Are New

Many people believe that because underwear is new, it must be clean. However, as pointed out by www.cleaninginstitute.org, this is not always the case. New items can have lingering chemicals and bacteria that only washing can remove.

2. Washing Will Ruin the Fit

While it’s true that washing can sometimes change the fit or feel of certain fabrics, the benefits of removing harmful substances far outweigh this concern. Proper washing can actually help maintain the integrity of the fabric over time.

3. One Wash Is Enough

Some believe that one wash will suffice for all types of underwear. However, according to experts in www.washguides.com, it may be necessary to wash certain items multiple times to fully remove all chemicals and dyes.
